LIQUID-DISPENSING DEVICE.

Specification of Letters Patent.

Patented Aug. '7, 1917.

Application filed February 9, 1915. Serial No. 7,095.

To all whom it may concern:

Be it known that I, W'ILLIAM C. MORRILL, a citizen of the United States,residing in the city of New York, borough of Manhattan, county and Stateof New York, have invented a certain new and useful Liquid- DispensingDevice, of which the following is a specification.

This invention is a liquid dispensing device, the same being adapted foruse, more particularly, in connection with a container wherein liquidsoap is stored free from contact with air in order to precludedeterioration and coagulation of the liquid material.

In my prior Patent No. 911,834, granted Feb. 9, 1909, there is discloseda form v of soap machine embodying a container, usually of glass, and adelivery device positioned at the bottom portion of said container andoperable by an upward movement of the hand, said delivery device acting,mainly, to forcibly eject a limited predetermined quantity of the liquidmaterial directly into the palm of the hand. Said delivery device asdisclosed in said patent embodies a chambered body within which operatesa piston adapted to control the flow of the liquid material into thespace below it and to forcibly eject said material, said piston beingnormally depressed by a spring and being provided with a depending stem,the latter serving as a means for operating the piston at will and as acut-off or valve when the piston is raised.

The delivery device of the aforesaid patent is composed of machinedmetal parts which are, comparatively speaking, expensive of manufacture.

My present invention embodies a construction, certain parts of which arecomposed of stamped or spun metal, thereby.

securing economy of manufacture, one of said sheet metal parts being soconnected to the glass container as to afford protection to the fragilematerial of said container, thus minimizing the breakage thereof andimparting a desired finish to the machine More specifically speaking,the present invention embodies a closure or head composed of sheet metaland provided at its perimeter with a flange and at its center with adepending tubularboss, combined with a piston having a stem dependingthrough a dellvery opening provided centrally in said tubular boss, anda sleeve, the latter being separate from the closure and attached in asuitable way to said closure head so as to cooperate with the piston andthe pressure spring for said piston. Said sleeve performs severalimportant functions, 2'. 6. it is positioned for frictional contact withthe piston, thus acting as a guide for said piston in the verticaltravel thereof; it houses or incases the spring and retains said springnormally in contact with the piston; it is provided in the sides thereofwith ports positioned in such relation to the travel of the piston as toinsure the inflow of the liquid material into the space below the pistonas the latter is lifted; it is flanged and perforated at the top toafford a seat for the spring and to produce a port through which theliquid material, displaced by the upward travel of the piston, is freeto flow out of the sleeve, and it is positioned in contact with a gasketadapted to serve as a seat for the piston when the latter is depressedby the spring, so that the sleeve retains the gasket in a predeterminedposition and precludes movement of said gasket with the piston as thelatter travels within the sleeve.

The flanged closure or head is attached in any preferred way directly tothe container, the latter being composed usually of glass. Saidcontainer is, or may be, provided at the bottom with a neck portionagainst which the flanged closure is fitted in a manner to embrace saidneck portion, thereby affording protection to the fragile material. Theconnection between the closure and the container may be of a permanentnature or of a separable nature; but should the parts be separablyconnected, it is preferred to provide the container neck with a grooveor grooves and the flanged closure with a stud or studs so as tocooperate as a bayonet lock, in which case a tight joint is securedbetween the container and the closure by the inter- Figure 1 is avertical section through theclosure and the liquid-delivery device, thecontainer being omitted for the sake of clearness, and the piston beingshown in its normal lowered position. 1

liquid outlet, and through said liquid outlet the liquid material isforcibly ejected by the action of a piston.

17 designates a sleeve, composed of sheet metal. The sleeve ispreferably uniform in diameter, except that the top portion of thesleeve is provided with an inwardly extending flange 18 in which isformed an opening 19 adapted to serve as a vent through which liquid mayflow freely on the upward travel of the piston, the liquid containedwithin the Fig. 2 is a vertical section, similar to F-igfsleeve beingdisplaced by the piston on said 1, withthe piston in a raised positionso as to compress the spring, thereby placing thev piston in positionfor ejecting the liquid material on the downward movement.

A container for liquid material is indicated in Figs. 6 and 7 by thereference numeral 10,'said container being provided at its bottomportion with a contracted neck 11. It is apparent that the container maybe of any desired shape and size and, further, that it may be composedof any appropriate material, such as glass.

12 designates a closure adapted to be applied to the neck 11 of thecontainer for the purpose of tightly closing the opening in said neck ofthe container, thus precluding the leakage of the liquid material fromsaid container. The closure 12 is'provided with a central depending boss13 and with an upstanding flange 14, said boss and the flange being.integral with the closure. It is preferred to make the closure with theflange and the boss from a single piece of sheet metal which is punched,spun, or otherwise treated so as, to impart to the closure the form anddimensions illustrated in Figs. 1, 2, 8 and 9. The boss 13 is hollow orcham- ,bered and it depends centrally from the closure. The rim 14extends upwardlyfrom the closure at the edge portion thereof, the

diameter of the rim exceeding the diameter of the tubular boss.

The tubular boss 13 is provided with an inwardly extending flange 15 atthe lower end thereof and in said flange 15 is provided an opening, 16,the. latter constituting the upward travel. The lower part of sleeve 17fits snugly within the chambered boss 13, said sleeve 17 being fixed tosaid boss 13 in a suitable way. It is apparent that the sleeve may besoldered to the boss or it may be attached by a screw-thread thereto,but the detailed connection of the sleeve to the boss may be varied asdesired.

The sleeve is provided in one or both sides thereof with vertical slots20, the latter serving as ports to admit liquid freely tothe space belowthe piston when the latter is in the raised position of Fig. 2, but whenthe piston is in the normal position, as in Fig. 1, said piston cuts offthe flow of material into the'space below it, whereby the piston acts ina threefold capacity; first, as a means for controlling the flow ofliquid material into the space below the piston, as well as to providefor the inflow of air to the inteice is provided with an integraldepending stem 22, the latter passing loosely through the opening 16which constitutes. the delivery port. Theexternal diameter of the solidpiston head 21 is slightly less than the internal diameter Of the fixedsleeve 17, whereby the piston fits snugly within the sleeve and is freeto move vertically therein. The external diameter of the rod 22depending from the piston corresponds practically to the diameter of theliquid port 16, and when the piston and the rod occupy the raisedpositions of Fig. 2, said rod 22 practically closes the port 16, wherebythe liquid ma terial admitted into the space below the piston isprecluded from flowing out through the port 16. The rod 22 thus acts asa opening 16, at which time the liquid port is,

opened by a beveled or chamfered portion 23 prov'i ded on the surface ofthe stem 22, said, ehamfered portion 23 reducing the diaameter of theupper portion of the stem so that the stem when the piston is lowereddoes not close the port 16, but, on the contrary, the chamfered portion23 provides a space between the surface of the stem and the edge of theliquid opening 16, through which space the liquid material is free topass when said liquid material is acted upon by the piston on thedownward travel thereof.

24 designates a gasket positioned within the tubular boss and restingupon the inturned flange 15 at the bottom of said boss. This gasket iscomposed of any suitable material and it forms a seat for the piston 21.The under side of the piston is provided with a rib or flange 25,preferably tapering or V-shaped in cross section, said rib or flangebeing embedded within the material of the gasket under the pressure ofthe spring 26 acting upon the piston. The ta pering flange cooperateswith the gasket 2 1 in securing a liquid-tight joint at the bottom ofthe delivery device, and thus the piston acts in the capacity of a valvein cutting off the outflow of liquid and in precluding the leakage ofliquid. In my prior patent the gasket is liable to become displaced bythe movement of the piston stem through it, said gasket adhering to thepiston stem and partaking of the movement thereof. In my presentconstruction, however, this objection is overcome, for the reason thatthe gasket 24 is in contact with the lower edge of the fixed sleeve 17,said sleeve acting to retain. the gasket in a predetermined position andin contact with the flange 15 whereby the gasket cannot follow themovement of the piston stem.

The spring 26 is-housed or incased within the upper part of the fiXedsleeve, said spring being seated at its upper end against the inturnedflange 18 of said sleeve, whereas the lower end of the spring is incontact with the piston for the purpose of forcibly depressing saidpiston, the pressure of the spring upon the piston being suflicient toforce the tapering rib or flange 25 into firm engagement with the gasket24.

It is apparent that the closure 12 is fitted to the neck 11 of thecontainer in such manner that the flange 14 of the closure embraces theneck, thus imparting a desirable finish to the container and bringingthe flanged closure in such relation to the container that the metal ofthe closure aflords protection to the fragile material of the container.The metal closure is adapted to be fastened permanently to the glasscontainer by cementing the parts together, but when it is desired toseparately attach the closure to the container I employ a series ofstuds 27 on the flanged closure and a series of grooves 28 in the neckof the container. The grooves 28 are inclined slightly and open at oneend through the edge of the neck, as at 29. In connecting the closure tothe neck the flange 14; is

tioned on-the upper face of the closure 12,

and within the flange 14: thereof, and by drawing the closure and thecontainer together with a wedging action the gasket 30 is compressedbetween the edge of the container neck and the closure, therebycompressing the gasket and securing a tight joint which precludesleakage of the liquid material from the lower part of the container.

In the normal position of the parts the spring 26 acts upon the pistonto depress it into contact with the gasket 24, the stem 22 depending asuitable distance below the tubular boss 13, thus exposing the stem 22to convenient access, said piston 21 closing the lower end of the slots20 in the fixed sleeve 17. To operate the piston. the hand ispositioned, palm upward, below the stem 22, and by moving the handupwardly the stem and the piston are raised to the position of Fig. 2,the spring 26 being under compression. Upon such upward movement of thepiston the stem 22 slides through the open ing 16, whereby the stem actsto close said opening 16, and at this time the piston 22 is raised withrespect to slots 20, whereby air is free to flow into the space belowthe piston so as to ultimately find its way into the interior of thecontainer and at the same time the liquid material in the container isfree to flow through the slots 20 and substantially fill the spacewithin the fixed sleeve 17 below the piston. -VVith the parts in theirraised positions, the liquid fills the space below the piston and thestem 22 closes the aperture 16, thus precluding the outflow of theliquid material and retaining said liquid material in the path of thepiston. By removing the hand pressure from the piston stem, spring 26acts to quickly depress the piston and the stem, the chamfered part 23of the stem opening the liquid outlet 16, whereby the piston exertspressure upon the liquid during the downward movement of said pistonunder the action of the spring, as a result of which a limitedpredetermined quantity of liquid is forcibly ejected into the palm ofthe hand, i. c. the latter is spattered upon the hand so as to becomespread or diffused over it.

It is apparent from the description taken in connection with thedrawings that the closure and the sleeve can be manufactured rapidly andeconomically from punched, stamped, pressed or spun sheet metal.Furthermore, the parts are simple in construction, easily and quicklyassembled, and practical experience shows that the device is efiicientand reliable in operation.

Having thus fully described the invention, what I claim as new, anddesire to secure by Letters Patent is:
